Python的安裝部署

(1) centos6安裝python2.7

sudo yum -y install python-devel openssl openssl-devel gcc sqlite-devel

wget

tar zxvf python-2.7.6.tgz

cd python-2.7.6

./configure --prefix=/usr/local/python2.7 --with-threads --enable-shared

sudo make

sudo make install altinstall

sudo ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib

sudo ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib

sudo ln -s /usr/local/python2.7/bin/python2.7 /usr/local/bin

sudo /sbin/ldconfig -v

# ok

python2.7 -v

安裝pip.

wget  --no-check-certificate

tar xf distribute-0.6.49.tar.gz

cd distribute-0.6.49

python2.7 setup.py install

sudo /usr/local/python2.7/bin/easy_install pip

#ok

/usr/local/python2.7/bin/pip install ***

[root@localhost ~]# python

python 2.6.6 (r266:84292, aug 18 2016,15:13:37)

[gcc 4.4.7 20120313 (red hat 4.4.7-17)]on linux2

>>> exit()

執行which python命令，你會發現預設的python是在/usr/local/bin/python

目錄下，實際上我們新安裝的python也在這個目錄下

[root@localhost ~]# which python

/usr/bin/python

[root@localhost ~]# python

python 2.6.6 (r266:84292, aug 18 2016,15:13:37)

[gcc 4.4.7 20120313 (red hat 4.4.7-17)]on linux2

>>> print"hello,world"

hello,world

>>> print "python2.7"

python2.7

>>> 1+2+3

6>>> exit()

開始練習python指令碼

[root@localhost ~]# cd /tmp

[root@localhost tmp]# vim hello.py

#!/usr/bin/env python

# -*- coding: utf-8 -*-

name = raw_input('please input yourname:')

print "hello,world!","ilove meinv",name

print"1+2+3+4+5+6+7+8+9+10=",1+2+3+4+5+6+7+8+9+10

print 'i\'m learning\"python\"!'

print '''line1

line2

line3'''

print '中文測試正常'

[root@localhost tmp]# chmod +x hello.py

[root@localhost tmp]# python hello.py

please input your name:tangtang

hello,world! i love meinv tangtang

1+2+3+4+5+6+7+8+9+10= 55

i'm learning "python"!

line1

line2

line3

中文測試正常

(2) centos6安裝python3.5

wget

tar xf python-3.5.0.tgz

cd python-3.5.0

./configure --prefix=/usr/local--enable-shared

make

make install

ln –s /usr/local/bin/python3 /usr/bin/python3

在執行python之前需要配置庫：

echo /usr/local/lib >>/etc/ld.so.conf.d/local.conf

ldconfig

執行演示：

python3 --version

python 3.5.0
